Hi,
I am debugging the SCT3288 HDK right now which is programmed with the STM32F405RGT6 microcontroller within it. While I was trying to debug the SCT3288 HDK, UART comport is not being detected because the firmware is got updated with some other file so I need to flash the required bin file to reset the MCU by using STM32 cube programmer application. So can you please help me to flash the bin file by using SWD mode or JTAG mode. As I am not finding the required pins for the JTAG in SCT3288 HDK.
Thanks,
Kind Regards,
K. Manikanta Sai Srinivas.
Solved! Go to Solution.

Again, please show good, clear photos.

You still haven't said what "comport"!
Again, it's not an ST board - so you can't expect people on the ST forum to know about it, or be able to provide detailed support.
Again, a diagram and/or photos would be clearer than trying to describe in words.

An ST-Link would be the obvious choice - but any SWD programmer which supports STM32 would do.
What do Sicomm recommend for use with their kit?

This thing?
SCT3288 - Advanced Baseband Processor | CMLMicro
It's probably locked in RDP 2 and not user-programmable. Contact the manufacturer.
If it isn't locked in RDP 2(it probably is), connect BOOT0 high during startup and use the SWD pins or the supported UART pins for programming. You'll need the schematic to find the appropriate nets.

You mean something to do with this: http://www.sicommtech.com/en/products/sct3288.html ?
That's not an ST product so, as @TDK said, you'll need to contact the manufacturer for support with it:

That's nothing to do with ST - you need to contact Sicomm for support with their tools!
Do they not provide schematics?

Hi,
I got the SWD pins over that SCT3288HDK and I have connected SCT3288HDK SWD pins to STM32 NUCLEO L476RG SWD pins which are there in CN4 header in NUCLEO-L476RG eval board and I am trying to flash the bin file by using STM32CUBEPROGRAMMING application. And I am able to flash the bin file in the respective stm32L476RG microcontroller with the STM32CUBEPROGRAMMING application and as I have been connected SWD pins which are there in the SCT3288HDK SWD pins, we are assuming that the STM32F405RG which is the onboard microcontroller for the SCT3288HDK is not getting programmed with the bin file .We are saying this because we are unable to detect the comport even though it is a proper bin file to be flashed. Can you please suggest me inorder to get the comport.
Thanks,
Kind Regards,

Again, The SCT3288HDK is a Sicomm product - nothing to do with ST - so you really need to be going to Sicomm for support with their kit.
Sorry, I don't follow that mass of text!
I can't make out what you have successfully programmed, and what you haven't.
A diagram would be more helpful.
And some good, clear photos of your setup.

Why are you assuming that?

What COM port? This isn't a sicomm support forum, not really anyone here familiar with their product.
F405 code will not run on an L476
The Nucleo's on board target must be disconnected to program external parts. Pair of jumpers, removed.
Are you sure the binary you are using is correct?
Perhaps use a stand-alone ST-LINK to see how that behaves / reports.

If you want to use the ST-LINK VCP you're going to need to snap off the top section and wire the UART to the TX/RX jumper point.
2025-05-20 3:35 AM
Yes I have been removed the 2 jumpers at CN2 to connect the external application. And the binary which I have been programmed is the proper one. Then also I am not able to detect the comport .So I will try to flash the bin file with SWD debugger. So can you please suggest the 4 pin SWD debugger .

Detect WHAT COM Port?
The ICs have UARTs.
If you need the IC to provide a VCP you need to connect via the USB interface and have a viable USB VCP Device firmware on-board.
If the .BIN lacks that, it's not going to work.
Did Sicomm provide this .BIN?
An authentic ST-LINK/V3 or V2 should work unless the part is protected. It won't address an issue with the .BIN being wrong.
